I'm heading out to the 2010 Woodward Dream Cruise on Tuesday, driving my '66 GTO there.

The caption is correct, as plant 16 was the Final Finish plant (I believe pinstriping was done there, for example); vehicles were shipped there after Plant 8 (the final assembly location). You might already know there were roughly 10 or 15 separate buildings, all co-located on the same property, each having a specific plant designation (this is fairly typical among the manufacturers here in Michigan).

However, I believe they misintrepted the number "55" - that was not "Line 55", but the build manifest sequence number for that specific car on the line. It was "Car number 55" on that build manifest, a (sort of) random start point but the numbers increasing sequentially after that point. The manifest sequence number tied the VIN, Body number, carrier number, order number, etc all together in one place, but was of no use after the vehicle left the assembly plant (that is, not like the VIN which would be forever affixed to that unique vehicle).

Perhaps Eric White (gtoric) can confirm or negate my thoughts.

I'll be out there probably Tuesday through Friday (but not Saturday) - if you would like, we could ride up to the complex and drive around, and I'll point out some of the various buildings and locations.
